Alright I need help. Alright I own a Randall Bass 500 head. (not sure what model it is, i'll get that tomorrow). I run it through a matching 2 x 15 cab. I'm pretty sure it's a 500 watt. I'm not getting enough volume still when I play with the band, and I thought 500 was more than enough. I run the head with gain on 5, Master Volume on around 8 (any louder and it gets overdriven), Treble on 8, Mids on 2, Mid Freq. on 5, Bass on 6, Bass Rollover on 8, and a 'W' shaped E/Q on both the head and my E/Q pedal. I'm trying to figure out what can I do to get the most volume out of this rig. Oh another is I play an Ibanez SR - 506 6 string with pickup dial in the middle, bass on 6, treble on 5 and volume on 10. Thanks in advance.
